Use with the patented AutoValve disc insert. This economical C-20 graphite crucible is created from an extruded graphite material that's well suited to working with silver, lower-karat yellow gold (14-karat or less), brass, bronze and other copper-based alloys. For white gold or higher-karat yellow gold, choose a crucible made from denser C-50 graphite. Graphite crucibles help scavenge any remaining oxygen from your melt, reducing oxidation of the metal and delivering cleaner casting grain and alloy. Design features five 1.8mm holes.\u003c\/p\u003e","brand":"Neutec","offers":[{"title":"Default Title","offer_id":50754452816218,"sku":"710759","price":625.15,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/710759.jpg?v=1742357378","url":"https:\/\/www.amadesa.com\/zh-cn\/products\/c-20-graphite-grain-making-crucible-for-j-zp","provider":"Amadesa","version":"1.0","type":"link"}
